WINDOW-BEAD FASTENER.

Application. filed May 1, 1911. Serial No. 624,510.

To all whom it may concern: l 3e it'known that I, JOHN B. DoLAN, ac1t1zen of the United States, residing at Central Falls, in the countyof Providenceand State of Rhode Island, have invented certain new anduseful Improvements in Window-Bead Fasteners, of which the following isa specification.

My invention relates to improvements in attachments for window beads,and the purpose of my invention is to provide for an attachment for awindow bead which will securely retain the bead in place, obviate thenecessity of sawing the end of the bead on a bevel, and be inexpensiveto attach. I ac complish these objects by a device shown in theaccompanying drawing, in which- Figure l is a perspective of a portionof an ordinary window sill having attached thereto a portion of a windowjamb showing the spline in position. Fig. 2 is a plan of a window sillshowing my attachment in position and a cross section of the windowjamb. Fig. 3, a vertical view of the window j amb, bead and attachmentand a partial vertical section of the window sill, and Fig. 4:, adetailjperspective of my attachment.

The same parts are indicated bythe same letters throughout the severalviews.

In all window beads in ordinary use the lower end is cut at a bevel toconform to the pitch or bevel of the window sill. As a result of this,each head in process of manufacture has to be sawed twice at the lowerendonce to obtain the desired length, and again to cut the necessarybevel. By virtue of the beveled end, the bead cannot be reversedendwise, nor from front to back, as the bevel will fit only in oneposition. Again, the ordinary window bead is con- 7 stantly warpingbyreason of the exterior surface being exposed to the atmosphere andpulling out from its socket.

By the use of my device the window bead may be reversed either endwiseor from front to back and in case ofsloping window sills the necessityof a double sawing, with the attendant waste of stock, is avoided, andthe bead is held securely in position and cannot move from its socket.

In Fig. 1, b is a portion of an ordinary window sill slopingin themanner in which window sills are ordinarily made; 03 is a portion of anupright'window jamb, and e a portion of a bead located therein, while arepresents my attachment.

In Fig. 2, d is a cross section of the win- I dow jamb; '0 the channelinto which the bead fits; a the bead, and a projecting prongs in 4tegral with the attachment a for the purpose of securing the attachmentboth to the window sill and to the bead.

Fig. 4 is a perspective in detail-of my device; a being the uppersurface thereof and a -a prongs struck up from the body of a by suitablemeans. It will be seen that the device a is wedge-shaped, that is, theback edge a is thicker than the front edge a, so that a when in positionupon the window sill, as in Fig. 1, will have its upper surfacehorizontal. The relative size of the attachment a is such as toapproximately equal the size of the cross section of the bead.

Fig. 3 shows mydevice in place ready for the bead to be forced down uponit. In this figure, crepresents the channel for the bead, ethe beaditself; e the lower end thereof and a my device in itsplace on thewindow sill with the prongs a driven into the window sill firmly, andanother prong a projecting upward ready to have the bead e forced downupon it, thus holding that securely in place also.

The exact number of projecting prongs, a is not material, so long assome project upwardly and some project downwardly so as to secure thebead,.and at the same time hold the device in place upon the windowsill.

My device is made preferably of malleable metal so that the prongs w"may readily be struck up from the body, as shown in Fig. 4.

While in the great majority of cases the bead will be wedge-shapedbecause by far the larger number of window sills are made sloping, asshown in the drawing, yet my device is equally applicable to a windows1ll which is horizontal. In that case, however,

,for the reception of the bead, said plate having one face fiatthroughout and against which the lower end of the beadabuts, sald platehaving its lower face beveled throughout to snugly fit against thesloping window sill, the bevel of said plate extending transversely withrespect thereto, and said plate further having transversely extendingequally spaced portions struck therefrom to provide fastening prongsprojecting in opposite directions with respect to each other and adaptedto engage in the bead and sill whereby the plate is secured in position,the

area of said plate conforming to the cross 10 sectional area of thehead.

In testimony whereof I affix my signature in presence of two witnesses.
